ME <br /> KLEINFELDER <br /> Method 8020. In addition lead,chromium, cadmium,and zinc were analyzed by inductively <br /> coupled argon plasma (ICP) spectrometer. The sample from B-8 was analyzed only for <br /> lead, chromium, cadmium,and zinc by ICP. <br /> Analytical Iaboratory results indicate that concentrations of TPH, oi? and grease, and <br /> BTEX constituents were not detected above laboratory reporting limits in the two samples <br /> analyzed from boring B-7. Concentrations of chromium and zinc; however,were detected <br /> in samples analyzed from both B-7 and B-8. Cadmium and lead were not detected above <br /> the laboratory reporting Iimits. <br /> In B-7, the sample collected at a depth of 16.5 feet had concentrations of chromium and <br /> zinc detected at 44.9 and 60.0 mg/kg, respectively. The sample collected from the bottom <br /> of B-7 (depth of 51.5 feet) had concentrations of chromium detected at 11.6 mg/kg and <br /> zinc detected at 39.5 mg/kg. In the background boring B-8, chromium and zinc were <br /> w detected at 33.0 and 35.8 mg/kg, respectively. Analytical results for the soil samples are <br /> summarized on Table 2. The .chain-of-custody form and laboratory data sheets are <br /> included in Appendix B. <br /> . <br /> F13-90-60 6 <br /> 1, . <br />
